Predation of N. melanostomus within a 3 h time-period on G. pulex (grey) and D. villosus (white). Gammarus pulex mean size (± SD) 11.8 ± 1.5 mm and D. villosus 18.3 ± 2.4 mm. [Asterisks indicate significant differences at p < 0.05 (*), p < 0.01 (**), p < 0.001 (***)]. Boxplots represent 25 to 75 % (boxes) and 5 to 95 % percentiles (whiskers). Circles represent outliers (exceeding 1.5 interquartile range); n = 12 per substratum trial)
